I have the same problem as Martin Schultze. When I add a certain construct with 3 indicators to my model and add more than one path from this construct the p-values and s.e. would disappear in the output.
I am a newbee in Mplus and may overlook something obvious but could you tell me what is the reason for that?
but what does "conditional" mean in this context. I am wondering why just this construct would make a difference while all others won't. Could you give me a hint where I can find this issue in the user manual?
Sorry to ask again but what does this mean? I tried to find out with the help of the Users Guide, Google etc. but could not find a hint. Does it mean:
1. Something is wrong with my dataset? 2. Some constellation which makes the model not computable? 3. Do I have to leave the construct out of my model in order to get p-values and fit indices or can I make this work somehow?
Please send input, data, output and license number to support so we can see exactly your situation.

Dear Dr. Muthen,
You said in the above posting "With WLSMV, standard errors and p-values for standardized parameters are not available for conditional models". Can I be reasonably confident in applying the p-values for unstandardized parameters to the standardized parameters? I am hoping to use the standardized parameters to compare the relative predictive value of each covaraite.
The p-values are different for unstandardized and standardized parameters because their sampling distributions are different. If you don't get p-values, you may be using an older version of Mplus where they were not available.
